Second and Third DWI in Denton County: What Changes and What the Defense Looks Like
A second or third DWI arrest in Denton County is not simply a repeat of the first. The charge level is different, the mandatory minimums are different, the prosecution’s approach is different, and the prior conviction itself becomes part of the prosecution’s case. Denton County is an active DWI enforcement jurisdiction. Denton PD, the Denton County Sheriff’s Office, DPS, and the departments serving Lewisville, Flower Mound, Highland Village, and the other cities across the county all feed cases into the same DA’s office and the same courts at the Denton County Courts Building at 1450 E McKinney Street.
Deandra Grant Law’s Denton office is at 1317 E McKinney Street, Suite 101A which is directly across the street from the courthouse. Managing Partner Deandra Grant has been defending repeat DWI cases in Denton County courts for more than 30 years. She holds a Master’s Degree in Pharmaceutical Science and the ACS-CHAL Forensic Lawyer-Scientist designation. Partner Douglas Huff holds the same designation.
How Prior Convictions Work Under Texas Law
Under Texas Penal Code §49.09, a prior DWI conviction or related conviction (intoxication assault, intoxication manslaughter, boating while intoxicated, flying while intoxicated) can be used to enhance a new DWI charge. For a DWI 2nd, the prior conviction is a punishment-phase enhancement: the State proves it only after the jury finds the defendant guilty of the current offense. For a DWI 3rd, the two prior convictions are jurisdictional elements that must be proven as part of the offense itself.
Deferred adjudication as a prior. Texas law permits the State to use a prior Texas deferred adjudication for DWI as an enhancement for a subsequent DWI charge. Out-of-state convictions must have elements substantially similar to the Texas offense to qualify. Each prior must be examined individually.

Second DWI in Denton County: Class A Misdemeanor
A second DWI in Texas is a Class A misdemeanor carrying up to one year in county jail and a fine up to $4,000. Two consequences set it apart from a first offense regardless of how the case resolves:
Mandatory minimum jail as a condition of probation. Even if the judge grants probation, a defendant convicted of a second DWI must serve a minimum of 72 hours in county jail as a condition of that probation. This cannot be waived by plea agreement or judicial discretion.
Ignition interlock. A second DWI triggers mandatory ignition interlock installation as a condition of bond from the moment of arrest and as a condition of probation.
Additional conditions of probation for a second DWI typically include community service hours, a DWI intervention program, no alcohol use, random testing, and license suspension up to two years.
Third DWI in Denton County: Third-Degree Felony
A third DWI in Texas is a third-degree felony. It is the same offense level regardless of whether it is a fourth, fifth, or subsequent conviction. The penalty range is 2 to 10 years in the Texas Department of Criminal Justice and a fine up to $10,000. A guilty plea to a third DWI is a felony conviction, with all that follows: loss of voting rights during sentence, loss of firearms rights, permanent felony record, and immigration consequences for non-citizens.
Mandatory minimum jail as a condition of probation. For a third DWI, the mandatory minimum jail period as a condition of probation is 10 days, with a maximum of 180 days. Community supervision at the felony level also carries mandatory ignition interlock, no alcohol use, random testing, community service hours, and a probation term that can extend to 10 years.

What the Defense Examines in Every Denton County Repeat DWI Case
The Prior Conviction
The State must prove each prior conviction beyond a reasonable doubt through certified court records. Sometimes the documents are incomplete or contain errors. If the prior cannot be proven, the enhancement fails and the charge reduces. An out-of-state prior that does not have elements substantially similar to the Texas offense cannot be used for enhancement. Every prior in a Denton County repeat DWI case is examined before any other defense strategy is built.
The Blood Evidence
Blood draws in Denton County alcohol DWI cases are typically analyzed by the Texas DPS Crime Lab in Garland. In drug impairment cases, specimens may go to the DPS Austin lab, Armstrong Forensic Laboratory, or NMS. Chain of custody, sodium fluoride preservative adequacy, in vitro fermentation risk, and headspace GC methodology are all subject to forensic examination. Deandra Grant’s ACS-CHAL designation and Master’s Degree in Pharmaceutical Science mean that evaluation happens at the level of the science.

The Rising BAC Defense
If alcohol was still being absorbed at the time of driving, the BAC at the time of the test may be meaningfully higher than the BAC while the defendant was behind the wheel. The rising BAC defense requires pharmacokinetic analysis which is exactly the kind a Master’s Degree in Pharmaceutical Science provides.
The Stop
Was there reasonable suspicion for the stop? Under Texas Code of Criminal Procedure Article 38.23, evidence obtained through an unlawful stop is suppressible with no good faith exception. Suppression of the stop means suppression of everything that followed, including the chemical test.
The ALR Hearing
The ALR hearing must be requested within 15 days of notice of suspension. In a repeat DWI case it is particularly valuable. Sworn testimony from the arresting officer creates a record that can be used in the criminal case. Missing the deadline means automatic license suspension regardless of the criminal outcome.
